Tips for Zone Comparison
- Compare zones one number apart to understand incremental differences (e.g., 6b vs 7b)
- The "a" and "b" subdivisions represent a 5°F difference in minimum temperature
- Growing days matter as much as temperature for crop selection
- Consider microclimates - south-facing slopes can be one zone warmer
